...I'm enjoying my purchase and still consider it worth it if you have other mods for this part to work with. I do not notice much of a difference in power although it helps my car's engine to run smoother

Install was easy. It definitely makes a whistling sound which varies with throttle position. I don't notice a power change. As of right now (about 2 weeks) my truck is recording about a .5 MPG increase. Not sure this will remain.
